Tortilla Taco Casserole

This recipe came about because I had ground beef thawed out for dinner ,but couldn't decide what to make with it..after checking out my refrigerator..I literally used all my leftovers to make this casserole. And my family said how good it was, and that the flavor was very good...and we should have it on our regular monthly menu. I did have some leftover rice, that I forgot to add to the scrambled beef..so next time I will use it.(I put the rice in the freezer).

Stack tortillas, wrap in a damp paper towel and microwave about 1 minute,just until warm and soft; keep covered.

Spoon a portion of the meat mixture down the middle of each tortilla and carefully roll up. Place seam side down side by side in the prepared dish.

Pour the sauce mixture evenly over the rolls and if you had any meat mixture leftover, distribute evenly over top of sauce.
Top with remaining cheese and onions.
Bake in oven for 20 minutes or until hot and cheese has melted.
